PowerSSR and ZeroCross Tails in one power cord for phase-controlled power to 120vac non-inductive loads with a microcontroller.

FEATURES
  • Combines the features of our PowerSSR and ZeroCross Tail s into one power cord device.
  • PowerSSR function provides fast solid-state triac switching suitable for ac dimmers and motor speed control. Arduino sample sketch or variable dimmer . Video demo.
  • ZeroCross Tail function provides zero-crossing detector with open collector output adaptable (external resistor required) to microcontroller logic level.
  • Control loads up to 450 watts, non-inductive, with a 3vdc (3ma) to 12vdc (30ma) steady or pulsed control signal.
  • Simple 3-wire low-voltage connections: PSSR in, Common, ZeroCross out. See  instructions .
  • Local LED indicator shows status of control voltage.
  • No exposed 120vac voltages and no dangerous 120vac wiring required. Plugs into standard NEMA 5-15R/P 120vac 3/2 prong household outlets, power strips and extension cords.

SPECIFICATIONS:
  • AC input: NEMA 5-15P Plug, standard 120vac with ground.
  • AC output: NEMA 5-15R Receptacle, standard 120vac with ground.
  • Load capacity: 120vac, 450 watts maximum continuous load, non-inductive.
  • Switching device: Solid-state triac, indefinite life expectancy.
  • DC input: 3vdc @3ma to 12vdc @ 30ma, terminal block accepts #14-30 AWG wire.
  • ZeroCross output: Open collector. Requires a resistor connected to the supply voltage of the microcontroller. Not to exceed 30vdc. Positive going sync pulse to supplied voltage.
  • Operate times: Suitable for 50/60hz phase control of incandescent and LED light strings.
  • DC to ac circuit isolation: Optically isolated to 5300Vrms. 
  • Indicator: LED indicates when dc side is energized.
  • Protection: AC side protected with 150vac MOV; DC side is transient free.
  • Mounting: Two #6 screws or free standing.
  • Environment: Indoor use only.
